Could someone please,tell me how to use nticedump 1.8 in SoftICE4.05?

1. which build of 4.05? 1.8 supports 334 only, use 1.10+ for newer versions.

2. what is the problem? the little info you provided (pretty much nothing) doesn't exactly help anyone to remotely guess your problem.... if it's about installing the thing at all, then here's a quick guide: copy the appropriate 'icedump' file and ntid.exe into your %systemroot%\system32\drivers\ directory (ie. where normally ntice.sys is itself). then simply run ntid.exe and your ntice should be patched, finally reboot (or if you haven't loaded ntice yet, simply start it manually).
